利用pycrypto处理AES加密解密_pycryptodomeaes mode_gcm解密文件

代码如下:

from binascii import b2a_hex, a2b_hex
from urllib import unquote
 
from Crypto.Cipher import AES
from Padding import appendSpacePadding
 
 
class AesHandler(object):
    def __init__(self, **kwargs):
        """
        key,id是30环境A0008的
        """
 
        self.key = kwargs.get("key", "!I50#LSSciCx&q6E")
        self.iv = kwargs.get('iv', "$t%s%12#2b474pXF")
        self.mode = AES.MODE_CBC
        self.BS = AES.block_size
 
    def encrypt(self, text):
        text = appendSpacePadding(text)
        cipher = AES.new(self.key, self.mode, self.iv)
        cipher_text = cipher.encrypt(text)
        return b2a_hex(cipher_text)
 
    def decrypt(self, text):
        cipher = AES.new(self.key, self.mode, self.iv)
        plain_text = cipher.decrypt(a2b_hex(text))
        return unquote(plain_text)
